   This method updates an entry with a new value, and returns whether the entry was
   update. If there are duplicate keys, only the first found element will get
   an updated value. Use QuickHashIntStringHash::CHECK_FOR_DUPES during hash
   creation to prevent duplicate keys from being part of the hash.
